Explanation of Solution
Given information :
Sara has 10 pound of dried fruit selling for
Pounds of mixed nuts selling for
Calculation :
Pound | Price per Pound | Total Price | |
Dried Fruit | 10 | ||
Mixed Nuts | |||
Trial Mix |
The total price for dried fruit is
The total price for mixed nuts is
The total price for trial mix is
Therefore, the rational equation is
Hence, the rational equation is
c.
